Which hole do you insert a tampon in

the one the blood comes out of lol :D don't worry I would ask my friend or mom for better detail but until you can figure out how to use tampons I recomend you use pads.

the vagina, their is only one hole

The vagina - closest one.

ok well I haven't started that why I wanted to know but thanks for yall help

There are two holes: your anus, and your vagina. Obviously you don't need to put a tampon in your anus, so you put it in the vagina. I'm assuming you know which hole is the anus--the other hole is the right one.

actually, there are three. the urethra (where urine comes out), the vagina, and the anus. so put the tampon in the middle one.

Right, of course there's the urethra, but there's no chance of getting a tampon in, so I didn't mention it.

...I'm pretty sure you can.

If you can fit a tampon in your urethra, there's something seriously wrong.

...it stretches...
...assuming you're not using a super plus size...
